. GRAIN-SHOCKER.

Specification of Letters Patent.

Patented Apr. 6, 1915.

To all whom it may concern:

Be it known that I, PHILIP C. KUHL, a subject of the King of England, residing at Medicine Hat, in the Province of Alberta, Dominion of Canada, have invented certain new and useful Improvements in Grain- Shockers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in grain shockers and more particularly to an apparatus to be used in connection with binders and receive the bundles of grain dischar ed therefrom forming them into shocks an de ositing the shocks at intervals along its pat of movement.

The primary object of this invention is to construct a shocker such as described which can be very readily applied or detached from a binder of any usual type or design.

Another principal object of this invention is the provision of a shocker employing the use of a vertically movable and rotary cradle with means for retaining bundles of grain therein in shock formation and operating the same so as to deposit the shock in an upright position upon the ground.

Another object of this invention is the provision of a shocker comprising a cradle aving a plurality of spring arms pivoted to its opposite sides and so constructed and enga e by a pair of cam plates that they will e moved to retain the bundles of grain deposited therein against displacement in shock formation an automatically release the same when the cradle is moved to its discharging position.

Still another object of this invention is to reduce a'shocker having a rotarv cradle Into which bundles of grain are deposited from a suitable conveyer, the said cradle bein so mounted that it will have an intermittent rotary movement so as to quickly pass over the shock which has been de osited upon the ground in order that it wi 1 not strike against the same from the rear'and knock it forwardly and then be slightly retarded in its movement to permit t e a paratus to pass entirely from over the s ock before it completes its revolution thereby preventing its striking the said shock from the opposite side and knocking it rearwardly.

A further object of this invention is to produce a shocker consisting of a wheeled frame in which is mounted a rotary cradle in such manner that the same will be raised and lowered through the medium of a pair of operating cams while being filled or dischargin the shock.

A stil further object of this invention is to improve and simplify devices of this character rendering them comparatively simple and inexpensive to manufacture, reliabile and efficient in use and readily operate With the above and other objects in view this invention resides in the novel features of construction, formations, combinations, and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved shocker. Fig. 2 is a rear view thereof. Fig. 3 is a top plan view. Fig. 4 is a section on the line 44 of Fig. 3. Fig. 5 is a detail of the cradle arm. Fig. 6 is a perspective of a certain operating lever. Fig. 7 is a perspective of another operating lever. Fi 8 is a detail view showing a portion 0 the elevator. Fig. 9 is a detail plan view showing such clutch mechanisms used in connection with this device and a sprocket wheel connected thereto, the mechanism being shown in one position. Fig. 10 is a view similar to Fig. 11 but showing the mechanism in a second position. Fig. 11 is a detail rear view of this portion of the mechanism. Fig. 12 is a section on the line 1-1-44 of Fig. 3. Fig. 13 is a section on the line 1515 of Fig. 3. Fig. 14 is a section on the line 1616 of Fig. 3.

Referring to the drawings by similar characters of reference throughout the several views the numeral 15 designates generally a portion of a conventional binder to the side bar 16 of which is secured a pair of adjustable collars 17, each of which is held against any undesired displacement therefrom by a set screw 18 and also provided with vertically extending lugs 19 for slidable engagement through a pair of eyes 20 formed upon the side bars 21 of a support ing frame 22. This supporting frame 22 is coupled intermediate its ends as indicated by the numeral 23 andis connected at its opposite sides by a plurality of longitudinally extending bars or braces 2%. The opposite ends of the bars 21 from those upon which the eyes 20 are formed are constructed to produce attaching members -25 which are secured in any suitable manner to the adj acent longitudinally extending side beam rigidly against any undesired displacement,

while the beams 31, 32, and 34; are connected by similar braces 36.- The rear ends of the bars 26 and 28 are connected by a short transverse rear beam 37,.to the rear side of which is secured a bracket 38 which supports above the upper edge of the beam 37 a hearing 39 in which is journaled for rotary movement a shaft 40. This shaft 40 has keyed to its rear end a sprocket wheel 41 and to its opposite end a beveledpinion 4:2 which meshes with a similar pinion/l3 keyed upon the stub axle latwhich is journaled in bearing as to the beam 26.

At 4:6 is a stub shaft which is mounted in a frame 4:8 having its inner end connected to a sleeve 47. The entire machine is supported on wheels 50.

-Fixed to the pinion 43 is a sleeve 54 which is provided on its end with clutch teeth 57. Slidably mounted on the shaft 44; and keyed "thereto for longitudinal movement is a sleeve 53 which is provided with clutch teeth adapted to engage the clutch teeth 57 and an integral flange 56 on the other end thereof against which spring (i-l rests. These clutch teeth are constantly urged apart by the spring 6% surrounding said sleeve. Slidable on the shaft 4% and rotatable thereon is a sprocket 59 to which is secured acam 66 having projecting from one end a sleeve 72 provided with clutch teeth which are adapted to engage clutch teeth on a sleeve 7 3 fixed upon the shaft 44;, the wheel 50 carrying said sleeve Q3. The sprocket wheel 59 is'connected to a sprocket wheel 60 keyed to a counter-shaft 61 journaled in bearings 62 located upon the forward ends of the beams 26, 29, 31 and 32 and interposed between the bars 33 and 3i, by a sprocket chain 63 so as to impart rotary movement to the said countershaft upon rotation of the sprocket wheel 59. Suitably supported on the' frame 37 is a rod whereon slides a lever 67 having a head 68 which is provided with an opening 70 to receive one end of a bent lever 70 which is iournaled in a bearing 71 the latter rotates.

. at both ends.

. 67 it will be observed from Figs, 9 to 14 that the sprocket wheel 59 is caused to move to the left of Fig. 9 by the action of said cam on the member 67so that the clutch teeth on the sleeves 5i and are engaged by such movement to the left. However, when the lower part of the cam is reached the spring (it forces the sleeve 53 to the right of said Fig. 9 so that the clutch teeth on the members 72 and T 3 engage. Thus the clutches are alternately engaged. By this means the elevating and tilting mechanisms are-alternately drivenas will behereinafter understood. When, however, it is not desired to drive the elevating mechanism itis simply necessary to adjust-the lever 70 so that 67 is moved to such position that the cam 66 no longer forces the sprocket 59 to the left as Then the teeth on the members 53 and 54 will be constantly disengaged and in consequence the elevator will remain inoperative.

The side of .the shocker frame adjacent the binder 15 has secured thereto by suitable straps 74 a pair of upwardly inclined side plates 75 which are held in spaced relation by cross bars 76. The ends of the plates 75 have journaled therein connecting shafts 77 to which are keyed adjacent the opposite ends thereof a pair of sprockets 78, each pair at the opposite ends of the frame being connected by sprocketchains 79 which are in turn connected by a conveyer band 80 which has secured to its outer sides slats 81 which engage the bundle of grain as it is deposited upon the said conveyor from the previously described binder. The bundles after being conveyed upwardly by means of the slats 81 are deposited into a cradle 82 which consists of a plurality of substantially semicircular ribs 83 of increasing diameters toward the forward end of the frame 27, which ribs 83 are connected by a plurality of rearwardly converging slats 84 thereby forming a cradle which is substantially semicylindrical in cross section being tapered toward its rear extremity and open This cradle 82 is supported upon a crank shaft 85 which is bent intermediate its length in substantially U-shaped formation as clearly illustrated by the numeral 86 to conform to the cross-sectional shapelof the cradle, while the upper end at one terminal of the said U-shaped portion is bent horizontally as at 87 and then downwardly and rearwardly at an angle as indicated by the numeral 88 to a point in spaced relation above the bearing 88' at which point itjis engaged by a bar 90 which holds it '1 against any undesired longitudinal displacement. 7

f The extension 89 of the shaft '85 has secured thereto a cam disk 91 which is adaptedto rest uponva bearing plate 92 secured to the beam 29' fora purpose to be later dis-- closed. The opposite end of the shaft 85 is extended rearwardly from the end of the cradle to produce an extension 92 similar to the before mentioned extension 88 and at its end it is off set as indicated by the numeral 93; at whichipoint it has keyed theretoa cam similar to the before mentioned cam disk-91 which engages a bearing plate 95 located upon the upper side of the rear end of the longitudinal beam 30. The-shaft 85 is held against 'any, undesired longitudinal movement at its extension 93 by'rneans of a bar'96 similar to the before mentioned slotted bar 90. v The terminal of the extension 93 has keyed thereto a forwardly extending arm 97 which engages the off set terminal 98 of anarm 99 similar in shape but considerably shorter in length which is formed upon a sleeve 100 keyed to the inner end of the stub shaft 48. This stub shaft 48 has further keyed thereon a sprocket 3.01 which is- 3.0

connected through the medium of a sprocket I chain 102 to a sprocket wheel 103 keyed to the countershaft 61 betweenthe-bars 31 and 32' whereby a rotary movement will be imparted'to the stub shaft 48. A pair of cam plates 104 and 105 are secured to the inner edges} of the said bars 29 and 30, respec- -tively,-by brackets 106 and 107 These cam fio . of grain may i tend outwardly 112 rotatably mounted upon the connecting -.'plat es-,-104 and 105 are bent outwardly at their'ends as indicated by the numeral 108 [for-engagement with arms 109 carried by a 1 plurality of closingfingers 110 which exfrom a pair of bars 111 and edges and into the cradle 82. Obviously,

' however, as the said cradle starts upon its rotary movement the engagement between the arms 109 and the curved extensions 108 of the cam' plates 10% and 105 forces the fingers 110' inwardly into engagement w th the bundles of grain located in the said cradle which obviously prevents their displacement therefrom when the cradle is moved to its discharging position. Simultaneously with this movement of the cradle, however,'the arms 109 move beyond the ends of the plates 104 and 105 which permits the Y.

fingers to be forced from engagement with the bundles by means of the springs 114,

thus freeing the shock. Assaid cradle is tilted through the medium of the crank shaft 85 the same is also lowered by the engagement'with the reduced portions vof the Game 91: and 94 with the bearing plates 92 and 95 at which position the off set portion 98 of the arm 99 moves along the slot formed in the arm 97 to a point adjacent the exten- I sion 93 of the shaft 85 which causes the said shaft to be rapidly rotated throwing said cradle 82 rapidly above the deposited shock thereby preventing any engagement with the said shock which would push the same forwardly causing it to be overthrown. As

the cradle moves rapidly upwardly the pin or off set 98'moves through the slot formed 1n the arm 97 away from the extension 93 of theshaft 85, thereby retarding the movement of the cradle 82 to such extent that the entire apparatus will pass from over the shock before the said cradle again assumes its horizontal position, prior to being refilled, which prevents the same from striking against the forward side of the shock and causing the same to be overthrown by suchv contact.

The operation of the device is as follows: The clutch member is thrown through the medium of the lever 70 in such position that the conveyor will be operated through the .medium of the drive wheel 50 which transfers the bundles of grain from the binder into the cradle 82- in such position that the heads of the said bundles will be located at the reduced end thereof. The lever 70 is then moved so as to throw the conveyer out of engagement with the said drive wheel and tothrow the countershaft 61 into engagement therewith. The rotation of the said countershaft obviously rotates the crank shaft 85 thereby tilting the cradle so that the heads of the bundles are arranged uppermost, which bundles'are insured against displacement by the means of the fingers 110 which are forced inwardly by the engagement of the arms 109 with the cam plates 104 and 105. As the cradle rotates the same will be lowered through the medium of the previously described cams 91 and 94: until when the cradle is in a vertical position the same will be at its lowermost position. Si-

multaneously with the arrival of the cradle in its vertical and lowermost position the arms 109 will pass beyond the ends of the plates IO l-Which releases the fingers 110 and permits the shock to bedeposited in an .upright position upon the ground. The cradle will be then rapidly rotated as the pin 98 is at the inner end of the slot formed in the arm 97 until the said cradle passes free from engagement with the upper end of the shock. At this position the cradle is raised through the medium of the cams and has the pin 98 passed outwardly with respect to the said slot formedin the arm 97 and the rotary movement of the cradle will be retarded clear the shock before the cradle is returned to its" normal position ready for refilling.

" Front the foregoing disclosure taken 'in' connection With the accompanying drawings', it will be manifest that a shocker of 'the. nature described is provided for which Will fulfill all the necessary requirements of such a device.
